i-polysilicon ine-grey metallic luster kunye nobuninzi be-2.32 ~ 2.34g / cm3. Indawo yokunyibilikisa 1410℃. Indawo yokubilisa 2355℃. Inyibilika kumxube we-hydrofluoric acid kunye ne-nitric acid, enganyibiliki emanzini, i-nitric acid kunye ne-hydrochloric acid. Ubunzima bayo buphakathi kwegermanium kunye nequartz. I-brittle kubushushu begumbi kwaye iphuka ngokulula xa isikiwe. Iba yi-ductile xa ifudunyezwa ngaphezu kwe-800℃, kwaye ibonisa ukuguqulwa okucacileyo kwi-1300℃. Ayisebenzi kwiqondo lobushushu begumbi kwaye idibana neoksijini, initrogen, isulfure, njl. Kwimeko yobushushu obuphezulu obunyibilikisiweyo, inomsebenzi omkhulu weekhemikhali kwaye inokusabela malunga nayo nayiphi na into. Ineempawu zesemiconductor kwaye iyimathiriyeli ebaluleke kakhulu kwaye igqwesileyo ye-semiconductor, kodwa umkhondo wemilinganiselo yokungcola inokuchaphazela kakhulu ukuhanjiswa kwayo. Isetyenziswa kakhulu kwishishini le-elektroniki njengesixhobo esisisiseko sokwenza iirediyo ze-semiconductor, iirekhoda zeteyiphu, iifriji, iiTV ezinemibala, iirekhoda zevidiyo, kunye neekhompyuter zombane. Ifunyaniswa ngekhlorin eyomileyo ye-silicon powder kunye negesi eyomileyo ye-hydrogen chloride phantsi kweemeko ezithile, kwaye emva koko i-condensing, i-distilling, kunye nokunciphisa.
i-polysilicon ingasetyenziswa njengesixhobo ekrwada sokutsala i-silicon enye yekristale. Umahluko phakathi kwe-polysilicon kunye ne-crystal crystal silicon ibonakaliswa ngokukodwa kwiipropati zomzimba. Ngokomzekelo, i-anisotropy yeepropathi zoomatshini, iipropathi ze-optical kunye ne-thermal properties zingabonakali kakhulu kune-silicon eyodwa ye-crystal; ngokweepropathi zombane, ukuqhutywa kweekristale zepolysilicon nako kungaphantsi kakhulu kunokubaluleka kwesilicon enye yecrystal, kwaye phantse akukho conductivity. Ngokumalunga nomsebenzi wekhemikhali, umahluko phakathi kwezi zibini zincinci kakhulu. i-polysilicon kunye ne-crystal silicon enye inokwahlulwa enye kwenye ngenkangeleko, kodwa uchongo lokwenyani kufuneka lumiselwe ngokuhlalutya isalathiso senqwelomoya yekristale, uhlobo lokuqhuba kunye nokumelana nekristale. i-polysilicon yimathiriyeli ekrwada ethe ngqo yokuveliswa kwesilicon enye yekristale, kwaye iyimathiriyeli esisiseko yolwazi lwe-elektroniki yezixhobo zangoku ze-semiconductor ezifana nobukrelekrele bokwenziwa, ulawulo oluzenzekelayo, ukusetyenzwa kolwazi, kunye nokuguqulwa kombane wefoto.
